Not my experience, girls first period in the middle of class, she was... special and didn't say anything. Sat there the whole time and when she got up there was practically a pool of it in the concave chair. My experience, in the locker rooms (they were devided into sections by rows of lockers) the row next to mine started screaming. Apparently someone in the gym class before us shat their pants and went commando leaving their underwear behind. We learned that when it flew over the lockers and nearly hit someone. They picked it up with a pencil and placed it just on top of the lockers, the other kids noticed. One went "what the -blam!- is that!?!" And yanked them down. The dried turd ended up hitting someone in the head.
